HTML markup errors and warnings
(Rescan now...)
Errors:
Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “ISO-8859-1” for attribute “charset” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
Malformed byte sequence: “e9”.
Malformed byte sequence: “92”.
Malformed byte sequence: “e8”.
The “align” attribute on the “img” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Malformed byte sequence: “f4”.
Malformed byte sequence: “e0”.
Duplicate attribute “alt”.
Malformed byte sequence: “c9”.
Stray start tag “link”.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
Consider avoiding viewport values that prevent users from resizing documents.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
